Cutting fire and brilliance, dark and light.
A beautifully cut diamond sparkles with intensity and fire. Cut
refers to the proportions and finish created when transforming
a rough diamond into a polished diamond.
Of the four Cs, cut has the most influence on a diamond’s
brilliance, radiance and beauty. Round is the most brilliant
shape, and also has the most demanding cutting standards.
To measure the proportions of a Hyde Park diamond, we use
the Sarin Brilliant Eye. The Sarin Brilliant Eye is a machine that
is able to carefully and consistently measure every facet and
angle, as well as provide an accurate and detailed printout of
the quality and precision of a round diamond’s cut.
Each round diamond receives a Sarin cut grade from 0, being
the most brilliant, to 10, the least brilliant. This extra step is
just one way Hyde Park takes the mystery out of evaluating
and comparing stones, and also assures that you’re getting
the most beautiful diamond.
When a diamond has been cut to ideal proportions by a
master cutter, it will refract light internally from one facet to
another, and release the light through the top. This creates
the enchanting sparkle and brilliance that make diamonds
so desirable.
Every Hyde Park diamond is either ideally (0) or premium
(1-2) cut. We don’t sell any stones that are cut too shallow
or too deep, and we don’t recommend any round brilliantcut diamond with a Sarin grade above 4.

Ideal Cut
Light is refracted
from one facet
to another and
is released only
through the top
of the diamond,
creating amazing
brilliance and fire.

Too Deep
Light is refracted
through the
opposite side of
the pavilion, rather
than the top of the
diamond, resulting
in lost brilliance.
The center of the
diamond will
appear dark.

Too Shallow
Light passes
through the pavilion
without ever being
refracted. The
diamond appears
glassy and dark.

It’s remarkable that a characteristic so subtle can have such
a dramatic impact on a diamond’s value. But truly colorless
diamonds are the most rare and exquisite of them all.
To the untrained eye, most gem-quality diamonds appear
colorless. But actually, there are minuscule differences in shade
— the result of trace elements combining with carbon over the
diamond’s million-year formation.
To determine its true color, every Hyde Park diamond is
graded in an accredited, internationally recognized gemological
laboratory. It is viewed on its side under balanced white light and
assigned a color grade according to a “Master Set” of diamonds
provided by the Gemological Institute of America (GIA).

Clarifying beauty.
While many diamonds are incredibly beautiful,
no two are alike. Most diamonds have flaws,
called inclusions, which are unique to each
diamond. Inclusions can be crystals, feathers
and lines generally not seen unless magnified.
Clarity is determined by the absence of
inclusions – the fewer the inclusions, the more
rare and more valuable the diamond.
Clarity grades are determined by the number,
size, color and location of inclusions. The
smaller and less visible the inclusions, the
higher the diamond’s grade.
A gemscope is a type of microscope used for
examining diamonds. It allows inclusions to be
easily seen and evaluated, so when you choose
your diamond, you can do so confidently. We
provide a gemscope for you to use, because
you can’t choose the right diamond without
seeing everything that makes your diamond
beautiful and unique.

A weighty, but enviable, choice.
The most obvious factor of a diamondâ&#x20AC;&#x2122;s value is its size. However,
two diamonds of equal size can have completely different values
because of the other Cs: cut, color and clarity.
As with all precious gems, the weight or size of a diamond is
measured in carats. One carat is equal to 200 milligrams. When
weighing diamonds, a 1.00 carat is divided into 100 points;
therefore, a diamond of 25 points is also described as 0.25 carats
or a quarter of a carat.
Every Hyde Park diamond is weighed when it is loose, or free from
any mounting, so it will be accurately weighed.
As a diamond increases in size, its rarity increases, which also
increases the price-per-carat exponentially. Therefore, a two-carat
diamond is more than twice as valuable than a one-carat diamond
of the same quality and characteristics.

Shape is often mistaken with the technical term “cut.”
The precision of a diamond’s cut determines its beauty,
brilliance and fire. The shape of a diamond is limited only
by the skill and imagination of the craftsmen. The beauty
and brilliance of any shape is determined by the precision
of the cutting and polishing process.

Although the round diamond is the most popular and
brilliant diamond shape, there are beautiful shapes for
diamonds that give each its own unique characteristics.

Whatever shape you prefer, when you come to Hyde Park,
